Open Label Treatment Extension Study With SAR245408 or SAR245409 as a Monotherapy or as a Combination Regimen

The duration of the study for an individual subject will include:

1. Baseline assessments: within 7 days prior to the first dose of IMP.

2. Study treatment period(s):

Subjects will start study treatment at the beginning of the initiation or extension
periods based on the length of prior therapy with SAR245408 or SAR245409

- if <2 cycles, start with initiation period; subjects must complete all the visits
in the initiation period before moving to the extension period.

- if ≥2 cycles, start with extension period; duration of extension period is
unlimited.

- Subjects who will take a SAR245408 or SAR245409 daily dose higher than their
established dose of SAR245408 or SAR245409, respectively, in the parental study
will enter the study on Day 1 of the initiation period.

- Subjects who had dose interrupted in the parental study but fulfill parental
protocol criteria to restart IMP treatment will enter the treatment-extension study
on Day 1 of the initiation period.

- Subjects who fulfill the parental study criteria for IMP treatment continuation but
have ongoing Grade 2 AE(s) will enter the treatment-extension study on Day 1 of the
initiation period.

Subjects may continue to receive study treatment until disease progression, unacceptable
toxicity, withdrawal of consent, or until commercial supplies of SAR245408 or SAR245409
are available to them outside of the clinical trial

3. Follow-up assessments: 23 to 37 days after the last dose of IMP.

Inclusion criteria :

I 01. Males or females enrolled in Phase 1 or Phase 2 studies of SAR245408 or SAR245409 as
monotherapy or in combination with other regimens who have complete data collection for the
primary endpoint(s) of the parental study or who are being treated beyond the parental
study cut-off and meet all the criteria to continue to be treated per the parental
protocol.

I 02. All sexually active subjects (male and female) must agree to continue to use accepted
methods of barrier contraception (ie, condoms) during the course of the study and for 3
months after discontinuation of study treatment. For women of childbearing potential and
for men who can father a child, a second method of contraception in addition to a barrier
method is recommended. Hormonal contraception should be avoided in subjects taking
SAR245408 due to possible drug-drug interaction.

I 03. Female subjects of childbearing potential must have a negative pregnancy test at
baseline. Females of childbearing potential are defined as sexually mature women without
prior hysterectomy or who have had any evidence of menses in the past 12 months. However,
women who have been amenorrheic for 12 or more months are still considered to be of
childbearing potential if the amenorrhea is possibly due to other causes, including prior
chemotherapy, anti-estrogens, or ovarian suppression

Exclusion criteria:

E 01. The subject discontinued the parental study due to toxicity

E 02. Ongoing Grade 3 or higher Adverse Event (AE)

E 03. Ongoing Serious Adverse Event (SAE)

E 04. Subjects with ongoing dose interruption for any reason unless the subject fulfills
the criteria in the parental protocol for restarting IMP. In such case subject will start
the treatment-extension study on Day 1 of the initiation period

E 05. The subject has any of the following laboratory values ≥ Common Terminology of
Adverse Events (CTCAE) Grade 3

- Absolute neutrophil count (ANC),

- Platelet count,

- Hemoglobin,

- Bilirubin,

- Serum creatinine or calculated creatinine clearance,

- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST),

- Fasting plasma glucose (FPG),

- Prothrombin time/international normalized ratio (PT/INR) and activated partial
thromboplastin time (aPTT)

E 06. The subject has a baseline corrected QT interval (QTc) >481 msec or if a subject has
had a QTc interval increase of ≥ 60 msec from parental protocol baseline to an absolute
value of > 470 msec

E 07. The subject has a known allergy or hypersensitivity to components of the study
treatment formulation(s)

E 08. The subject is pregnant or breastfeeding
